Key Takeaways:
- Ketamine is not an opioid: Ketamine works on NMDA receptors in the brain, not opioid receptors, which means it belongs to a completely different drug class than opioids like heroin or prescription painkillers.
- Different mechanism, different risks: Unlike opioids, ketamine typically does not cause respiratory depression, but it can still be dangerous due to dissociation, impaired judgment, and potential for misuse or psychological dependence.
- Medical uses are legitimate and expanding: Ketamine is used as an anesthetic and, in controlled clinical settings, for treatment-resistant depression, but only under strict medical supervision.
- Misuse and addiction potential still exist: Even though it isn’t an opioid, ketamine can still be abused recreationally and lead to substance use disorder, especially with repeated or high-dose use.
Question:
Is ketamine an opioid?
Answer:
Ketamine is often misunderstood because of its association with pain relief and sedation, but it is not an opioid. Instead, it is a dissociative anesthetic that primarily affects NMDA receptors in the brain. This distinction is important because opioids act on opioid receptors and carry a high risk of respiratory depression, whereas ketamine does not typically suppress breathing in the same way. However, ketamine still carries significant risks, including impaired perception, dissociation, and the potential for psychological dependence when misused. Medically, ketamine has legitimate applications, including use as an anesthetic and as a rapidly acting treatment for severe, treatment-resistant depression under controlled conditions. Despite these benefits, recreational use can lead to addiction and harmful behavioral effects. Understanding that ketamine is not an opioid helps clarify its risks and appropriate medical role, but it should still be treated as a controlled substance with real potential for abuse when not properly supervised.

As the opioid epidemic continues to plague the nation, many people find themselves concerned about the risks these drugs can pose. As a result, it has become easy to misidentify other drugs as contributors to the opioid problem.
One of these commonly misconstrued substances is ketamine. Of course, while ketamine is not an opioid, these drugs can have similar effects. In addition, ketamine can still be dangerous when misused. Understanding exactly what ketamine is and how it works can help keep you and your loved ones safe.
What Is Ketamine?
Ketamine is a dissociative anesthetic that can produce hallucinogenic effects and create an altered state. The drug is known for its ability to distort perceptions of sight and sound, as well as affect the body, making those who use it feel disconnected and out of control.
Ketamine is typically used by injecting the substance directly into the bloodstream. As a short-acting “dissociative anesthetic,” it allows patients to feel disconnected from their surroundings and physical discomfort when used in a medical environment.
However, some people may use this drug illicitly for its ability to produce feelings of sedation, hallucinations, pain relief, and detachment. Ketamine abuse refers to the recurring, unsupervised use of ketamine outside of its intended clinical or veterinary boundaries. Illicit users often take much higher, dangerous doses to achieve an intoxicating, hallucinogenic effect, and the drug works quickly, with noticeable physical and behavioral changes often appearing within minutes of ingestion. This drug has even been used to facilitate sexual assault due to its ability to cause immobility and amnesia.
In 1999, ketamine became classified as a Schedule III non-narcotic substance under the Controlled Substances Act. Currently, it maintains an accepted medical use for short-term sedation and anesthesia. Recently, it has been made available as a nasal spray for treatment-resistant depression in certified medical environments.
However, it is important to understand that, even with its clinical applications, ketamine maintains a potential for abuse, as well as physical and psychological dependence, and should not be used recreationally.
Is Ketamine an Opioid?
Despite common misconceptions, ketamine is not an opioid. It is important to understand the difference between these two classes of drugs, as they work in very different ways and have distinct effects.
Opioids such as morphine, heroin, and fentanyl work by binding to opioid receptors in the brain and spinal cord, mimicking the effects of natural endorphins. This allows them to relieve pain, as well as produce feelings of euphoria and sedation. However, these effects also make opioids highly addictive.
Ketamine, on the other hand, acts as a noncompetitive NMDA receptor antagonist, affecting glutamate levels in the brain. This primarily produces dissociative effects, causing those who use the drug to feel detached from their bodies and surroundings.
Like opioids, this drug can be used medically for pain management, depression, and other conditions, as well as produce negative side effects if not taken properly. Ketamine also has the potential for abuse, but dependence and withdrawal are less common than with opioids.
Therefore, it is crucial to remember that even though both ketamine and opioids can offer pain relief, they function through entirely different mechanisms and come with varying sets of risks and benefits.
Is Ketamine Addictive or Linked to Substance Abuse Disorder?
As a controlled substance, ketamine is legally recognized for its potential for abuse and addiction. Substance use disorder can affect anyone, though the risk is higher for people with a family history of addiction or those who start using substances at a young age. The drug’s long-lasting and euphoric effects, along with signs like agitation, depression, cognitive difficulties, unconsciousness, amnesia, involuntary rapid eye movement, and dilated pupils, can make it difficult to stop using ketamine once a person has started.
With prolonged use, the brain can become dependent on the presence of ketamine in the system to function normally. Once this dependence has formed, stopping the use of ketamine can be extremely difficult without help. Long-term abuse may also harm the mind and lead to cognitive decline, severe mental health disruptions, and Hallucinogen Persisting Perception Disorder (HPPD). Chronic use can also severely inflame and scar the bladder wall, causing Ketamine Bladder (Ulcerative Cystitis). The risk of overdose also rises with illicit ketamine, especially when it is mixed with depressants or contaminated with fentanyl, which can cause respiratory depression, bradycardia, seizures, coma, and death.

What Is Ketamine Therapy?
Ketamine therapy is a treatment approach that works by administering low doses of ketamine to those who are struggling with various mental health conditions. Some of the most common conditions treated with ketamine therapy include treatment-resistant depression, anxiety disorders, and post-traumatic stress disorder (PTSD).
Administering low doses of ketamine produces a short-lived high with the potential to trigger a mystical experience for the person. This trigger can be accompanied by a subsequent positive change in their motivation, cognition, and behavior.
Current research suggests that ketamine therapy can help provide valuable insights and profound changes in a person’s consciousness. Treatment can also help some people to better understand and manage their mental health conditions.
With that being said, some people may not be a good candidate for ketamine therapy. This includes children, women who are pregnant or breastfeeding, and those with a personal or family history of psychosis or schizophrenia.
Individuals who have experienced adverse reactions to other dissociative anesthetics in the past may also want to avoid ketamine therapy, as this can put them at risk of experiencing unpleasant side effects.
It is essential to speak with your doctor or a certified treatment provider if you are considering participating in ketamine therapy. Royal Life Centers can help you understand your treatment options and whether ketamine therapy is the right fit for you.
